The scattering of light is slightly more pronounced in the evening than in the morning due to the air being warmer, and the increased level of dust due to daytime activity.  The result is that the sky will be tend to be 'redder' in the evening than in the morning, all other things being equal.
...And its claws are as big as cups, and for some reason it's got a tremendous fear of stamps! And Mrs Doyle was telling me it's got magnets on its tail, so if you're made out of metal it can attach itself to you! And instead of a mouth it's got four arses!
